I want to play many songs alternating with a question to the participants. I guess this is possible using limesurvey, please correct me if I'm wrong. Searching the forum I found the code for the jplayer. now I'm wondering:
1. can I track the participants' key presses (in combination with the time stamp of the song) ?
2. is it possible to end a song when a predefined key is pressed?
3. is there a limit to the size of the playlist?

I really hope this is possible so I can use limesurvey for my experiment!

Yes, this is all possible but involves far too much JavaScript for a forum post.

thank you for your reply!
I will see if I can solve it on my own within a few weeks(no JavaScript experience so far), otherwise I would pm you.
